Hi guys im pretty new to this.. I recently bought a 91 4runner with 22re in it.. when i got it it was pretty rough.

now the problemes im having is
-loud ping after 2500rpm
-ive got power in first gear after that no power
-boggy when giving gas
-very bad gas milage
-and when i hit the brake real hard im all over the road

heres what ive done
-calipers,pad,rotors,service rear drums
-bleed all the lines
-plugs,wires,cap,rotor
-timing chain,water pump,oil pump
-both tie rods,idler arm,4 ball joints, wheel alingment

Does anybody have an idea what some of these problemes can be??? ive look for days

Sounds like a vaccumn leak from or around the brake booster. Try searching around the forum for a bit this is pretty common and many threads cover these symptoms. 22re's are a bit finicky when leaks in the vaccumn systom occur. by the way welcome. post some pics!

https://www.yotatech.com/forums/f116...hlight=seafoam read this and try it, it should help out your engine and then go from there on figuring it out after you try it. Might check all of your bushings and make sure there is no slack in the front end parts. WElcome to youtatech and hope this helps you

blown diaphram in the brake booster maybe? plug up the brake booster line and see how the engine runs. (yes you will loose power brake) But they aren't working right anyway.

What do you mean by "All over the road"

pulls from side to side if i hit the brakes hard

I doubt the wandering is related to the power problem. Can someone confirm if the load sensing valve in the back would cause a wander? My guess is no, but I thought I would throw that out there. I would definately plug the vac line to the brake booster though, but block it off from the manifold side not the booster side. If problem goes away as far as power then hook the manifold side back up and block it off the the brake booster side. If problem returns, then the hose or the connection to the booster is bad, if problem is still resolved then the diapham in the booster is bad. In rare cases the check valve on hose to the booster will lock shut or is put in backwards as well. This will prevent vacuum supply to the booster. I can't remember if the toyotas have it or not, its 12 degrees outside and I don't wanna go check lol.

i had a set of tires before that made it nearly impossiable to drive on the highway every time i touched the brakes it would dart accrost the road

cool ill check the booster right now

toyotabull

I had a set of 38.5's do that to me, but they were wore and I think it quit doing it when I changed tires. Cant remember exactly what it was.

Timing or knock sensor would be my first bet.

xxxtreme22r

Dang RE's always forget they have the knock sensor. haha. But yeah that too.

on_campus15

thanks for the info
i just did the chain on it im positive the chain is bang on
i also did a valve adjustment..
anyone know how to test knock sensor...

jsn_stockard

Are you getting any codes? I would unplug the sensor and drive it a bit. If it acts the same there is a good chance its the sensor. Don't know if there is an actual test.

on_campus15

Well i just started my truck and the pinging noise is comming from the botom end...can my timing or knock sensor affect that..
or its the bearings in my botom end??

jsn_stockard

A bearing usually makes a knock, a ping is usually pre ignition (advanced timing) or possibly slack in the valve train. Sounding lower I would think timing needs to be retarded a bit

Change the fuel filter.
